gzip:stdin:不是gzip格式的tar:子返回状态1 tar:错误不可恢复:现在退出

我有一个bash脚本创建tar.gz并加密然后发送到驱动器.但是之后我无法打开.tar.gz.这是我的过程......

加密的Bash脚本.

#!/bin/sh

# tar the automysqlbackup directory
tar -zcf "red-backup-$(date '+%Y-%m-%d').tar.gz" /var/lib/automysqlbackup/

# encrypt the tar
openssl aes-256-cbc -a -salt -in "red-backup-$(date '+%Y-%m-%d').tar.gz" -out "red-backup-$(date '+%Y-%m-%d').tar.gz.enc" -pass 'pass:MySecretPWD'

# remove the original tar
rm -rf "red-backup-$(date '+%Y-%m-%d').tar.gz"

# upload to google drive
gdrive upload --file "red-backup-$(date '+%Y-%m-%d').tar.gz.enc" -p "jofhriout849uioejfoiu09"

这意味着该文件实际上并不是一个gzip压缩文件 - 或任何类型的gzip压缩文件 - 尽管它被命名为一个.

当您下载文件时wget,检查指示Length: unspecified [text/html]哪些显示它是纯文本(文本),并且它应被解释为html.检查wget下面的输出 -

这样确认您没有收到gzip文件.

对于正确的文件,wget输出将显示Length: 185515842 (177M) [application/x-gzip]如下所示的输出 -

以上显示gzip已下载正确的应用程序文件.

您还可以file,head,less,view实用程序来检查文件.例如,HTML文件会给出以下输出 -

[root@XXXXXX opt]# head jdk-8u144-linux-x64.tar.gz
<!doctype html>
<html lang="en">

<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link href="/css/print.css" rel="stylesheet" media="print">
    <link href="/css/main.css" rel="stylesheet" media="screen">
    <link href="/css/font-awesome.min.css" rel="stylesheet">

上面显示它确实是一个HTML页面,我们试图解压缩/解压缩 - 这是无效的.如果它确实是一个正确的zip文件(本质上是二进制文件),那么输出head就会产生垃圾 - 如下所示 -
